Wherein "Dan's" definition of pompous appears to be "I haven't come across it while reading my manga comics".
Particularly benighted examples of his apparent lack of any cognitive function whatsoever are his rationale for listing amygdala and seppuku. Or you may be amused by Dan's complete inability to understand nuance. This is a person who believes that a myrmidon is the same as a lackey, that tendentious is a synonym for biased, someone who does not understand the difference in meaning between offensive and invidious, doesn't know what synecdoche, prelapsarian, or saturnine mean.
Many folks with Dan's middle-school level vocabulary might try to do womething to augment it (you know, like read a book or two). Instead, the ignorant slagass macaroon goes on the internet and attempts to make a virtue of his ignorance by mocking those who know more than he does.
